Thanks for such a good thread and informative posts!
I'm getting the gear together while waiting for 10 Erupters to arrive, and have a very noob question. I've looked around but can't find an answer.
I'm not sure how the miners work so don't know whether there is any advantage of using USB3.0 vs UCB2.0 hubs. (for running 10 Erupters of a USB hub or two). I'm guessing no, but to be sure...
No there is no advantage to USB 3.0 vs 2.0. These are USB 1.1 devices.
If you plan on using CGMiner DO NOT get USB 3.0 hubs as that support is still in development.
What you need to pay attention to is the Power Supply of the USB Hub. People have been using the Anker 10 Port USB 3.0 hubs because they have a 4 Amp power supply so they can put 8 Block Erupters per Hub. I am using 7/5 Port Rosewill USB 2.0 Hubs which have a 2 Amp Power Supply so I can put 4 Block Erupters per Hub. Each Block Erupter draws .5 Amp.
So unless you modify a Hub you cannot put 10 devices on a 10 Port Hub, not safely/reliably anyway.
